This invention relates to roofingv cleats for prepared roofing more particularly adapted for use with rooting which is surfaced with y material such as slate,fine gravel and gritt. the like.

Cleats as constructed heretofore have had` centrally disposed upwardly projecting stift'- eningV ribs but underneath were quite smooth. For roofing made of plain asphalted felt such cleats are adapted to make good contact. When, however, such roofing felt is surfaced with slate, fine gravel or the like the fiat smooth portions of the cleat rest on the tops of the particlesof slate or other surfacing grit giving a poor grip Vand allowunder the cleatV around the particles of grit.

The principal object of this invention is to provide means for obtaining a better grip and more satisfactory contactbetween the cleat and the roofing felt there beneath than has been possible heretofore.

To accomplish this sharp projecting ridges are formed on the underside of the cleat capable of being forced between the slate or f until the supporting layer of asphalt is reached.

One of the objects of forcing a portion at least of the cleat intocontact with the asphalted felt is to prevent flow of water under the cleat especially opposite the nail holes and thereby reduce the liability of roof leakage. Y

Other and further important objects of this invention s will be apparent from the disclosures in the specicationand the accompanying drawings. Y Y

The invention (in apreferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings;V j Y Figure l is a perspective view of a portion of a roof covered with prepared roofing held in position bymy improved cleats.

Figure 2 is a plan view of the cleat itself. Figure 3 is asection on the line III-'III of Figure i.V

Figure 4 is a section on the line VIV-IV of `Figure 3.

f V Figure' is a 2, formed therein. ,As

section onftheline V-V of ;F1gure:3.=. r i i i As shown on .the drawings: i i The cleaticonsists of ametal stamping in strip form l'iaving upwardlyextendingcentrally disposed stiffening projections., lv and these projections are arched both transversely and longitudinally of the strip the latter isstiffened throughout such lengths of the strip as theseprojections extend. i Between the projections l and 2 are fiat portions 3 which allow the strip at such parts to be bent to meet changes in level of the roofing due to overlap of the sheets. The cleats are held in place by nails 4 driven through holes 5, preferably arranged centrally in the projections l and 2, into the sheathing 6 on which the roofing felt 7 is laid. To secure better grip and contact between; the cleats and the roofing felt downwardly extending V-shaped ridges orl projections 8 arestamped in the side Aportions 9 of the strip on either side of projections l and 2. Preferably these are arranged to over-` lap the holes 5 for the nails 4 for the pur-f pose of reducing the liability of water running down the roof reaching the liolespmade in the roofing felt by the nails 4. llVhen first laid the nail may fill the hole it inakesA in the rooling but in course of time it is apt to rust. especially if there is free flow of water under vthe cleat to the nail every time rain falls. These V-shaped ridges are adapted to be forced in between the particles of slate or Vgravel to contact with the asphalted felt therebeneath.

These V-shaped ridgesl 8 also aid in Venting the roofing sheets from moving transversely of the cleats. To aid in pre venting Vlongitudinal relative movement the precleats are provided with transversely and downwardly extending V-shaped portions, l0.

If desired rounded or pointed downwardly j and I, therefore, do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim as my invention:

A roofing cleat for use with prepared roofing material and adapted to be bent over overlapping edges of the material, the said cleat comprising a metallic strip having a plurality of spaced portions arched both transversely and longitudinally to form elongated ribs centrally of the cleat with a Hat portion along each side and at each end thereof, said flat portions having longitudinal downwardly extending projections parallel to the said ribs and spaced from either side thereof,Y and transversely disposed downwardly extending projections intermediate spaced from the said ribs.

In testimony whereof I have hereunto subscribed my name at Bronxville, Westchester County, New York.
